APPARATUS FOR PROVIDING BOXES WITH CLOSURES.

I Specification of Letters Patent.

Patented Dec. 1'7, 1912.

Application filed December 2, 1911. Serial No. 663,633.

JENKINS, citizen of the United States, residing at Washington, in theDistrict of Columbia, have invented certain new and useful Improvementsin Apparatus for Providing Boxes with Closures, of which the followingis a specification, reference being had therein to the accompanyingdrawing.

The object of this invention is to provide an improved automatic machinefor rapidly supplying open paper receptacles with paper closurescemented in place. For illustration the receptacles chosen arepreviously formed short cylindrical tubes, and the apparatus is employedfor closing one end ,of each tube by cutting a disk from a strip,flanging, and

inserting it after suitable adhesive has been applied.

In the drawings Figure 1 is a side elevation of a machine embodying theinvention. Fig, 2 is an elevation of the same machine, looking from theleft of Fig. 1. Fig. 3 is an enlarged plan view of the central portionof the machine with the upper portion of the frame and some other partsremoved. Fig. 4 is a vertical section show-' ing the disk cutting andclosure-inserting devices. Fig. 5 is a section on the line 5-5, Fig. 4.Fig. 6 is a side elevation, partly in section, showing paste applyingmechanism. Fig. 7 shows in elevation the left hand end of the apparatusseen in Fig. 6. Fig. 8'

shows in like manner the opposite end of the same apparatus. Fig. 9 is asection on the line 9-9, Fig. 8. Fig. 10 shows in elevation a portion ofa receptacle feeding wheel and its actuating mechanism. Fig. 11 is aside elevation of a cam hereinafter mentioned. Fig. 12 is a plan view ofa device for winding the scrap or remnant of the disk stripi Fig. 13 isa fragmentary elevation illustrating the discharge of the receptaclesfrom the wheel which carries them. Fig. 14.- is an end view of a scrapdrum seen also in Fig. 12. Fig. 15 is anelevation of devices. Fig. 16 isa plan view of the de- I vices in Fig. 15. Fig. 17 is a detail elevationof parts of the apparatus of Figs. 15 and 16.

In these figures, A represents the supporting frame of the machine, B areceptacle-carrying wheel, and G a power pulley,

moving parts of the machine. The wheel B is mounted upon a shaft Bdirectly below the shaft C and is provided with a series ofcircumferential radial pockets B each of which is open on one side andalso at its peripheral end. This wheel is rotated step by step by meansof.'the power shaft C (Figs. 1 and 2) spiral gears C C, an oblique shaft0*, gears C C shaft O crankplate C and a stud C which at each revolutionof the disk enters one of a series of open. recesses B in a ring B fixedon the lateral faces of the wheel B, the parts being so proportionedthat each movement of the wheel corresponds precisely to the angulardistance between the axes of any two consecutive pockets of the wheel,and during the time while the wheel is out of engagement, the wheel isheld immovable by a mutilated disk C, Fig. 10, this portion of thedriving device being a form of the wellknown Geneva movement.

The receptacle bodies D are fed into the pockets of the wheel by a chuteD, Fig. 2, down which they roll by gravity to enter the ascendingpockets as they reach in succession the plane of the wheels horizontaldiameter, and as they move upward with the wheel, they are preventedfrom leaving the pockets by a fixed plate D Fig. 2. Each body after itbegins its ascent with'the wheel has the interior of its outer endprovided with adhesive during a period of rest, by mechanism seen inFlgs. 1, 6, 7, 8, where E is a paste receptacle from which a wheel Etransfers adhesive to a rotary brush .E which is at proper times movedbodily in a direction perpendicular to its plane into and out of themouths of receptacles carried in the pockets B and each held temporarilyat rest in position to receive the brush. These devices are driven fromthe shaft C by gears F (Fig. 2), shafts F, F having universal couplings,and gears F F on the shaft F Thear F drives a gear F on the shaft F of te paste wheel E, while the' mounted on a shaft 0 for actuating-all the lwhich is'such that the shaft is pushed longimouth of the Waitingreceptacle, and as this aperture is of materially less diameter than thebrush, the peripheral flexible portion of the latter is retarded untilthe body of the brush is well within the receptacle when the continuedadvance frees the brush from the plate. When thus freed, the brushinstantly assumes its normal plane form and comes into contact with theinterior of the receptacle. The plate thus performs the double office ofremoving surplus paste from the brush and preventing the advancing brushfrom applying adhesive to the end face of the receptacle wall, thelatter result being of very great importance. As soon as the rotatingbrush has rubbed its glue or paste into the interior surface of thereceptacle, the camallows the spring to restore the brush to initialposition, and it is to be noted that the brush now carries little pasteand that in moving outward there is little tendency to leave'paste uponthe end of the receptacle. The plate is preferably removably held by thepaste receptacle so that it may be readily removed and cleansed, and itis so placed that paste dripping therefrom falls back into thereceptacle. After receiving its adhesive, each receptacle advances stepby step until it reaches vertical position at the top of the wheel whereit is supplied with a cup-like closure by devices to be described.

The closures are formed from, a paper strip G from a roll G, Fig. 1,this strip being fed forward by rollers G2 actuated from the power shaftby a pawl J connected with ordinary devices on the power shaft bya rod Jand engaging a ratchet J 2 on the shaft J of one feed roller. As thestrip leaves the feed rollers, it passes between plane plat-es G, G,Figs. 3, 4, and thence over a fixed die plate G, where its margins arestill held in grooves G. Here .a disk X is cut from the strip, while itis at rest, by the descent of a die G" carried by a long bar G hinged atG and having its free end raised and depressed at proper times by a rodGr provided at its upper end with a roller G engaging a cam G on thepower shaft C,

Figs. 2'and 11. Immediately after the cut-.

: ting of the disk a reciprocating plunger H,

out novelty, forming the disk into .cuprshape' concentric with the diebut of materially less diameter, is forced down. by devices withandforcing it into the waiting receptacle. On the retraction of theplunger, the wheel '13 brings another receptacle to place, and

the operation just describedis repeated. In

a rapidly running machine the working parts must be guarded from thescrap or unused portions of the strip. This is done by providing a reelor drum 1, Fig. 1, upon which the scrap is wound, the drum being drivenby an elastic belt I, from the power shaft, which permits slipping asthe roll of scrap increases- The drum is free at its outer end so thatthe material may he slipped off from time to time and thrown aside, andto facilitate attaching and detaching the strip, the drum" is providedwith an open slot I Figs. 12 and 14. Tension upon the strip is adjustedby means of a spring I and a thumb-screw I regulating the pressureof thespring upon the barb of the belt pulley 1 As a further protection,needed 1f the scrapstrip breaks, I provide below the strip a shallowtrough I extending from the die plate nearly to the scrap drum.

It may sometimes happen that by some chance an empty pocket arrives atthe top of the-wheel, and in such case it is desirable to avoid cuttingand forming a closure and depositing it in the unoccupied pocket.lDevices are, therefore, provided for automatically arresting thefeeding of the closure strip, in such cases, and in this case suchdevices hold the feed pawl J out of engagement at the proper time. Forlifting the pawl and holding it temporarily in raised position, I mounton the pawl-carrying arm J and just below the pawl, a rocklng block J 5having an arm J 6 which normally rests on a sleeveJ" sliding on the feedroller shaft and having a segmental peripheral flange J 8 alongside thevertical plane of the arm J. The sleeve is connected by a link J to alever J centrally pivoted at J to the frame and having at its oppositeend a roller J which a spring J urges toward the lower end portion ofreceptacles D when at rest in the wheel pocket which will at the nextadvanceof the wheel be brought beneath the cutting and insertingdevices. The flange J. is normally at a slight distance from the planeof the arm J but when the roller J the feed-pawl J from the ratchetwheel J and then travels along the periphery of the flange J until thearm J begins its return movement. One strip feeding step. is thusomitted, and the cutter and plungerat' their.

next succeeding movements find no stock beneath them. After the roller Jhas swung inward as described, it is pushed outward by the portion 4 oftlie wheel B at the next advance of the latter, and the flange J a'being thus withdrawn from the path of the arm J feeding goes on in thenormal man ner. 3

, As clearly appears in Fig. 2, the pockets B are so formed that whenthe receptacles D are descending after receiving their closures,they"tend to roll out of the pockets, and as soon as they pass the plateD they roll out of the pockets intoan inclined discharge chute K, Figs.1 and 2.

What I claim is: 1. The combination with a vertical wheel having aseries of peripheral, outwardly and laterally open pockets forreceptacle bodies,

of means for delivering such a body sidewise to each pocket upon theascending side of the wheel as it rotates, automatic means for rotatingthe wheel by steps equal to the distance between the azies of successivepockets, to bring each to rest at a predetermined point, and a die andplunger arranged to form and insert a closure in each body while thus atrest.

2. In apparatus of the class described, the

combination with a receptacle for adhesive, of a rotary shaft bearing adisk extending into the receptacle, a second shaft bearing a rotary diskbrush normally in contact with CHARLES FRANCIS JENKINS.
